Elle showed off a black dress by Philosophy di Lorenzo Serafini on Instagram, and we couldn't help but notice that it looked very similar to a certain Hollywood actress's iconic dress. (Hint: she went on to become a real-life princess).

Everything from the full skirt all the way down to the pearls around her neck reminded us Grace Kelly's look from The Country Girl. Have a look at both Elle and Grace's looks to see the resemblance for yourself.
